    Default File Structures and Format

    Hey guys. So I am working on a project and I need a FAST data structure to save/load TONS of data. As far as saving to files, it doesn't have to be human readable. I am wondering if anyone has any recommendations for me. I would LIKE to write it myself but if that's not possible, its not a huge deal. As far as the kind of data im storing, it is just integers, floats, doubles, etc.

    Using RandomAccessFile will give you control over where you read and write.

    I forgot to mention that I want it to be similar to a HashMap or something like that - keys and values...

    Then you'll need to do some design work.
